Reaktionsschritte
A 1M solution of DiBAIH (87.5 ml, 87.5 mmol) is added dropwise to a solution of methyl 2-heptyloxy-4-iodobenzoate obtained in Step a (14 g, 43.7 mmol) in toluene (450 ml), at 0° C. After stirring for 2 hours, a saturated solution of mixed tartrate of sodium and of potassium is added and then the desired product is extracted by addition of ethyl ether. The organic phase is washed with water, dried with magnesium sulfate and concentrated using a rotary evaporator. The product is purified by chromatography on a silica column, eluted with a heptane/ethyl acetate 9:1 mixture. After evaporation of the solvents, 13.64 g (90%) of the expected compound are recovered in the form of a yellow oil.
